` cHALK-HOLDER.

SPECIFICATION forming para of Letters Patent No. '720.240, dated February 10, 1903- Application led November 3, 1902. Serial No. 129,878. (No model.)

To ctZZ whom it may concern.-

Beit known that I, JOHN B. GURY, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented a certain new and useful Chalk-Holder, of which the following is such a full, clear,-V

My invention relates to devices for holding chalk such as is used ,by manufacturers of garments for marking out the patterns of the garments upon the cloth. Heretofore it has' been usual to use ilat pieces 'of chalk for this" purpose, the pieces `of chalk being held in the hand of the workman. Owing to the friable nature of the chalk it is necessary to make the pieces of chalk muchthicker than is re quired for the marking in order for the chalk to withstand the necessary pressure. This not only causes waste of the chalk, but consumes considerable of the workmans' time in sharpening the chalk, for if it is'not sharpened it will make too Wide a line upon the cloth. The pieces of chalk can alsoonly ne conveniently used when they are of considerable size, so as to be. readily held in the hand, and hence considerable waste of chalk is occasioned in throwing away the pieces after they become too small to be used.

The object of my invention is to provide a4 device for holding the chalk which will Yovercome these difliculties. I

In the accompanying drawings, which illustrate a device made in accordancewith my invention, Figure l is a side view. Fig. 2 is a section on the line 2 2 of Fig. 3. Fig. 3 isa top plan view, and Fig. 4 is an isometric projection.

Like marks of reference refer to similar parts in the several views of the drawings.

l0 is a thin metal plate, which is provided with upturned edges 11 of about the same or slightly less height than the thickness of the chalk to be held in the device. The plate 10 is also provided with lugs 12, in which is pivoted a second plate 13, similar in shape to the plate 10. This plate 13 is provided with a projection 14, which bears upon a spring 15, formed integra-l with the plate 10, and thus holds the two plates together when the device is in its closed position, and so holds the chalk in position in the device. In the plate 13 is formed a slot 16. 17 isa block of metal of about the thickness of the chalk. Thisblock 17 is provided with an upwardly-projecting square portion 18,v which'extends into a slot 16. The block 17 is engaged by a screw 19, having a large dat head 20. By pressing upon the head 2O with the thumb or finger the screwvll) can be turned Yto loosen or tighten the block 17.

2l represents the chalk,`which is in the form of a broad flat plate or slab, as is clearly seen `in the drawings.

In using the device the chalk is placed upon the plate 10, between the upturned edges 11,

and the plate 13 is closed down upon it, as shown in Fig. 3. The pressure of the plates caused by the spring 15 is suiticient to hold the chalk in position. The screw 19 is now loosened by means of the head 20 and the block 17 moved against the chalk until it is forced to project a proper distance beyond the edges of the plates 10 and 13, as shown in Fig. 3. The screw 19 is then tightened to hold the block 17 rmly in position. As soon as the' chalk is Worn down to the metal the screw 19 can again be loosened and an additional portion of the chalk projected beyond the holder. As only a small portion of the chalk projects beyond the holder, very thin chalk can be used, thus avoiding the necessity of sharpening the chalk and also saving alarge amount of time. The chalk can also be used until a very small portion remains.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. In a chalk-holder, the combination with a pair of plates pivotally connected aton'e end and arranged to leave an opening at theopposite end for the passage of the chalk, ofa spring for holding said plates in contact with the chalk, and an adjustable stop for forcing the chalk through said opening.

my hand and affixed my seal in the presence of the two subscribing witnesses.

2. In a chalk-holder, the combination with a pair of plates pivotally connected together, of a spring formed integral with one 0E said plates and acting upon the other to hold the 5 chalk in position, and a sliding member for XVi'onesses: projecting the chalk beyond said holder. L. B. BEACH,
